Question 332916: The horizontal sides of a rectangle are one half the length of the side of a particular square. The vertical sides of the rectangle are 4 cm more than three times the side of the square. If the perimeter of the rectangle is twice the perimeter of the square, what are the dimensions of the rectangle?
Can someone show me how to solve this please? It would be much appreciated.

let 2x = side of the square
:
horizontal sides of a rectangle are one half the length of the side of a particular square.
x = horizontal side of the rectangle
:
The vertical sides of the rectangle are 4 cm more than three times the side of the square.
3(2x) + 4 = (6x+4) vertical side of the rectangle
:
If the perimeter of the rectangle is twice the perimeter of the square,
:
rect P = twice square P
2x + 2(6x+4) = 2(4(2x))
2x + 12x + 8 = 16x
8 = 16x - 14x
8 = 2x
x = 4
:
what are the dimensions of the rectangle?
Rect dimension x by (6x+4); replace x with 4
you have:
4 by 28 is the dimension of the rectangle
:
:
Check by find the perimeter of each
Rect: 2(4) + 2(28) = 64
square: 4(8) = 32;
